The RMS brightness temperature sensitivity for each baseline for a frequency channel width \(\Delta \nu _c\)  and correlator integration time \(t_c\)  for an observed frequency \(\nu \)  is given by [1]}:
\(\sigma _N=\cfrac{c^2~T_{sys}}{\nu ^2 A_{eff}~\Delta \Omega ~\sqrt{2~\Delta \nu _c \Delta t_c}}~,\)
